Yet to the untrained ear the language used in the U.N. climate talks is about as comprehensible as Klingon. Before everyone's comfortable with the wording of a concept or idea, it's often turned into an acronym. COP stands for Conference of the Parties, referring to the countries that have signed up to the 1992 United Nations Framework Convention on Climate Change. The ADP is a subsidiary body created in Durban, South Africa, in 2011 for negotiations on the universal climate agreement that's supposed to be adopted in Paris. [...] recently it's been implemented as a strict division between rich and poor countries, where only the former are obliged to reduce their emissions. Not the prettiest of acronyms, it refers to efforts to protect forests, which when destroyed release carbon into the air, contributing to climate change. The plus sign was added in 2010 to indicate that three more elements had been inserted into the discussions: conservation of forest carbon stocks, sustainable management of forests and enhancement of forest carbon stocks.
